Serious Sam Fusion 2017 is a fresh build of Serious Sam games developed by Croteam!

The best part? If you own a Serious Sam game listed below you'll be getting a Serious Sam Fusion 2017 version of that game for FREE!

Serious Sam Fusion 2017 is also a central hub for existing (and upcoming) Serious Sam games that will enable seamless integration of new engine features, patches and upgrades.

Games available in Serious Sam Fusion 2017

  • Serious Sam HD: The First Encounter - now available!
  • Serious Sam HD: The Second Encounter - now available!
  • Serious Sam 3: BFE (coming soon)
  • VR versions of all games will be a part of Serious Sam Fusion 2017, too!

Please keep in mind that this release of Serious Sam Fusion 2017 is currently in beta; you'll experience extreme violence, inexplicable joy, some sadness, sometimes all at once, and, how shall we put it... eeerm, occasional bugs. Please use the official discussions page to let us know. Thank you!

What does it do?

Serious Sam Fusion 2017 will enable a lot of cool new features, like a common workshop and cross-game mods. All of the games can be started from one application, so you can jump between playing The First Encounter level to a Serious Sam 3 level and back without exiting the game. When listing game servers, servers playing TFE, TSE, SS3 – will all appear in the same list and you can vote map across games if you want. Oh, and VR games will be able to be played in multiplayer together with their flat counterparts!

Since there are so many changes and exciting new features, we'll just go ahead a list them here as bullet points.

Cool new features in Serious Sam Fusion 2017

  • All games now support SteamOS/Linux/OSX!
  • Split-screen!
  • 64bit executables
  • Support for Vulkan API (DirectX9 is now being removed)
  • Multithreaded rendering
  • The new "light-weight" savegame system - savegames are now saved much faster, are very small and stored in the Steam cloud, and savegames still work even if a level is changed in a patch, or if a mod is updated
  • Full support for all controllers including Steam controller, PS4 gamepads, all older DInput joysticks
  • Proper multimonitor support
  • Borderless window support
  • Customizable sound outputs
  • Proper 3D audio using a proprietary sound-mixer (the same approach as used in the old Classic games)
  • Improved physics engine with better handling of character movement
  • Texture streaming in all games
  • Much better modding support with customizable weapons and items, improved scripting (including better support for scripting networked games)
  • Lots of other improvements, optimizations and fixes

I didn't really expect this to work, but after getting some really annoying problems out of the way I managed to get the custom bloom pipeline integrated and working inside the game.

This means bloom is more pronounced now and responds a lot more to different brightness levels, giving everything a more dynamic and appealing look. On top of that, due to the somewhat "physically based" nature, it softens up the overall look and makes things blend together a bit more. (Also, the lens-dirt effect works way better now)

One of the downsides is that the game wasn't designed with more responsive HDR effects like this in mind, so some objects or textures have less then optimal brightness levels or colors: causing either too intense highlights or not being visible enough. To name a few:

  • some weapons and other surfaces have fairly bright reflections that can look a bit overkill (but turning down bloom intensity would make it practically invisible on other objects)
  • laser projectiles in general have "bad" brightness & color values
  • some things like torches/flames, a few projectiles types, particle effects, etc. could use more brightness to make them pop out better

But still, there's a lot of things that work suprisingly well, like:

  • lava textures in general
  • some enemy projectiles
  • pretty much anything that glows (glowing eyes, etc; highlighted objects are a bit bright, though)

Here's a bunch of screenshots of the new look in action. I hope they can convey some of the changes as well as the overall feel, since these are getting close to the intended final look:

As of now, there's no download, yet, sorry. There are still a few things that need to be done, including:

  • value tweaking
  • detecting the right current resolution (in this specific version I'm simply assuming 1080p)
  • detecting resolution changes (and reacting to them properly)
  • the new bloom is independent of the graphics settings. if the default bloom is enabled in the settings it's still rendered in the background but ignored (-> wasted performance)
    -> some elegant way to either prevent the original bloom from being rendered or a way to notify the user that they should turn it off, to ensure optimal performance
  • cleaner resource management
  • fixing some minor glitches
  • test if there are settings-combinations which break things
  • framework related things (might be too technical and boring to explain here in detail)
  • settings? (not really planned and probably not even needed)

After solving the most important ones, I think I'll release another test version.

That's it for now, cheers :)
